Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.
Reported lifecycle history
- Proposed
Five-building, 360 MW plan re-filed with Montgomery County in May 2026 (an earlier two-building proposal was approved in 2024). County public hearing scheduled for Nov. 12-13, 2026.
Underlying source
Source notes
Five-building campus proposed by California-based Atmosphere Data Centers on the site of the decommissioned Dickerson coal power plant on the Potomac River. Single-source record: the developer's own filings were not independently retrieved. As of 2026-09-10, status remains proposed. The record already captures the June 2026 six-month permit pause and July 28, 2026 18-month Council moratorium. Atmosphere also withdrew its legal appeal of Elrich's now-moot six-month executive-order moratorium after the Council's 18-month moratorium superseded it, and a separate county ordinance indefinitely prohibiting data centers was set to take effect 2026-08-17.
Reuses the retired Dickerson coal plant's existing transmission lines and substation infrastructure; the application also includes a utility-scale battery storage facility on the site.
